Audio and Video freezing, lagging and cutting out (Windows 10)

Hi, I know that there have been alot of posts about this issue, but I have tried everything. When I stream hd videos on (youtube, netflix or play any video games) my audio and sometimes video freeeze for 5 sec, and it happens around every 10 seconds, in addition sometimes the mouse also lags too and seems like the computer is about to freeze. This happened today after my computer got a blue screen of death (Kernel Security Failed Check). I have clean installed my graphic drivers, updated bios firmwear, check/updated my sound card, realtek audio device, I have tried everything but nothing seems to be working, I was wondering if I am forced to rma the laptop or would this issue be solved with a clean install or even better a fix that wouldnt cause me to do either of these things. In addition I have noticed that my graphics card had a big decrase in performance, specifically prior to today my card was getting 120fps solid on CSGO and LOL but now it only gets around 98 fps.

In addition I ran sfc /scannow for my harddrive and it said that Windows Resource Protection did not find any violations

Thank you for your help,

Alex

Not sure if this is one of the things you have tried but lagging and freezes can sometimes happen if your Hard drive is turning off because of power management settings. Try turning this off by going into the Advanced power management settings:
